By Chris Mooney, Washington Post. For GSS Climate Change chapter 10. Excerpt: A large group of climate scientists has made a bracing statement in the journal Nature Climate Change, arguing that we are mistaken if we think global warming is only a matter of the next 100 years or so — in fact, they say, we are locking in changes that will play out over as many as 10,000 years. “The next few decades offer a brief window of opportunity to minimize large-scale and potentially catastrophic climate change that will extend longer than the entire history of human civilization thus far,” write the 22 climate researchers, led by Peter Clark, from Oregon State University. ...“In hundreds of years from now, people will look back and say, ‘Yeah, the sea level is rising; it will continue to rise; we live with a constant rise of sea level because of these people 200 years ago that used coal, and oil and gas,’ ” said Anders Levermann, a sea-level-rise expert at the Potsdam Institute for Climate Impact Research and one of the paper’s authors. “If you just look at this, it’s stunning that we can make such a long-lasting impact that has the same magnitude as the ice ages.” The key reason for this is that carbon dioxide stays in the atmosphere for a very long time before being slowly removed again by natural processes. “A considerable fraction of the carbon emitted to date and in the next 100 years will remain in the atmosphere for tens to hundreds of thousands of years,” the study noted.  ...In 10,000 years, if we totally let it rip, the planet could ultimately be an astonishing 7 degrees Celsius warmer on average and feature seas 52 meters (170 feet) higher than they are now, the paper suggests. There would be almost no mountain glaciers left in temperate latitudes, Greenland would give up all of its ice.... Still, anyone observing the world’s recent mobilization to address climate change in Paris in late 2015 would reasonably question whether humanity will indeed emit this much carbon....  https://www.washingtonpost.com/news/energy-environment/wp/2016/02/08/what-the-earth-will-be-like-in-10000-years-according-to-scientists/
